In Fig. 5 and Fig. 6, said gear mechanism 38 is by being fixedly installed on that first bevel gear 43, axis on above-mentioned the 4th spindle unit 33 is configured on the diameter line of above-mentioned gear ring 37 and constituting with a pair of second bevel gear 44,44 of above-mentioned first bevel gear 43 engagements and with the third hand tap gear 45,45 of these second bevel gear, 44,44 one rotations, and second and third bevel gear 44,45,44,45 of one is rotated and is bearing in freely on the trailing wheel support 25a.
A pair of third hand tap gear 45,45 is the meshing along circumferentially spaced two positions at interval of above-mentioned gear ring 37 that is bevel gear, gear mechanism 38 be constituted as gear ring 37 along circumferentially spaced two positions at interval to these gear ring 37 transmitting rotary power.And first bevel gear 43, second bevel gear 44,44 and the third hand tap gear 45,45 that constitute said gear mechanism 38 are compared with the periphery of gear ring 37 when being configured in side-looking and are positioned at inboard position as shown in Figure 5.That is, said gear mechanism 38 is configured in as a whole to compare with the periphery of gear ring 37 and roughly is positioned at inboard position.
Next the effect of present embodiment is described.Trailing wheel WR is being carried out in the rear wheel suspension device 18 of suspension, the front end of upper arm parts 22 is bearing on the pin plate 17... of vehicle frame F by axle, and these upper arm parts 22 rearward extend, the rearward end that is linking these upper arm parts 22 on the top that axle is supporting the knuckle parts 25 of trailing wheel WR rotationally, the front end of lower arm components 24 is bearing on the above-mentioned pin plate 17... by axle, and this lower arm components 24 is at the lower direction rear extension of upper arm parts 22, the rearward end of this lower arm components 24 is attached at the bottom of knuckle parts 25 rotationally, an end that on upper arm parts 22, is linking rear shock absorber unit 26, the rearward end of lower arm components 24 links with above-mentioned knuckle parts 25 rotationally in the position of comparing with the trailing wheel support 25a of above-mentioned knuckle parts 25 on the front, and the other end of above-mentioned rear shock absorber unit 26 and lower arm components 24 link.
Formation by such rear wheel suspension device 18, the structure of guaranteeing the vehicle frame F rigidity can be concentrated on the front end axle support of upper arm parts 22 and lower arm components 24, and do not need to guarantee the rigidity of the remaining part on the vehicle frame F, and, additionally do not need the part of linkage component etc. just can access advanced shock absorbing characteristics, thereby can avoid the increase of number of spare parts.
In addition, because compare place in the outer part when the linking department of lower arm components 24 and above-mentioned knuckle parts 25 is configured in side-looking with the periphery of above-mentioned trailing wheel WR, so can make knuckle parts 25 link the trailing wheel support 25a of the left and right sides that is configured in trailing wheel WR, the structure of 25b with becoming one, rear shock absorber unit 26 can be configured in the C place, width direction central position (with reference to Fig. 3) of vehicle frame F.
In addition, because an end of the above-mentioned rear shock absorber unit 26 that tilts to the front upper place is attached on the upper arm parts 22, the other end of this rear shock absorber unit 26 is attached on the lower arm components 24, so can carry out the setting of the good advanced person's of passing ability damping behavior.
In addition, because but rear wheel drive axle 19 is the parts that are made of first to fourth spindle unit 27,29,31,33 that two universal joints 28,32 by flexing link, so can improve the design freedom of rear wheel drive axle 19, and, can constitute rear wheel drive axle 19 at an easy rate by use universal joint 28,32, and the volume of rear wheel drive axle 19 is not increased.
Have again, because gear mechanism 38 is set between the gear ring 37 and rear wheel drive axle 19 that is fixed on coaxially on the trailing wheel WR, compare with the periphery of gear ring 37 when first bevel gear 43, second bevel gear 44,44 and the third hand tap gear 45,45 that constitutes this gear mechanism 38 is configured in side-looking and be positioned at inboard position, said gear mechanism 38 as a whole, be configured in the periphery of gear ring 37 and compare the position that roughly is positioned at the inboard, so can reduce the volume of gear mechanism 38.And, gear mechanism 38 be constituted as gear ring 37 along circumferentially spaced two positions at interval to these gear ring 37 transmitting rotary power, even therefore increase driving force, also can suppress the increase of the volume of gear mechanism 38, thereby can suppress the maximization of rear wheel drive device.
Embodiments of the invention more than have been described, but the present invention is not limited to the foregoing description,, can carries out various design alterations without departing from the invention.
